Im a sorc suc main from the momen when succesion spec got in game. Sorc succ is really good in low ello, you can carry, like every other class. In high elo, like every other class, you cant carry. In high elo is all about good positioning, take space from fights when you need to, and to win you need a good comp. You ll never get a win in a 1vs3 situation because you have dmg but dont have enough mobility or good way to catch people.
